WASHINGTON Institute of Applied Materials Jiangsu Teachers University of continuous efforts, has developed its own set of comprehensive recovery of gold and silver from electronic waste precious metals and other wet techniques, through dissolution, reduction, refining, drying and melting, etc. Process, the product with gold (silver) content can reach the international No. 2 gold (silver) standard.
According to different types of waste and gold and silver content at home and abroad, the recycling technology of gold and silver from electronic waste mainly includes three types: pyrometallurgical technology recovery, hydrometallurgical technology recovery and biological recovery.
At present, Nanjing Jinze Metal Materials Co., Ltd. has regenerated and reused organic waste such as copper and other organic wastes in electronic waste, and has achieved good disposal in the process of recycling. However, in the process of recycling organic waste such as copper and other non-ferrous metals and plastics, components such as circuit boards containing precious metals such as gold and silver cannot be effectively recycled according to current equipment and processes, which affects the economic benefits of the company and causes Waste of resources. To this end, the company fully relies on the technological advantages of Jiangsu Institute of Technology and other scientific research institutions, using the newly developed advanced technology, the two sides cooperate to implement the annual processing of 300t electronic waste recycling gold and silver and other precious metal industrialization projects.
At present, some world-famous electronic product manufacturers such as Motorola and Samsung Electronics have started to cooperate with Nanjing Jinze Metal Materials Co., Ltd. to recover precious metals from scrap products and semi-finished products.
High Speed Intelligent Paper Cup Machine
The working principle of our Paper Cup Machine is that a main motor drives the whole machine to work, which realizes the perfect integration of chain and cam structure. Now the machine uses a single aluminum plate to replace the previous three plate machine, which greatly reduces the machine failure rate and reduces the training time for the operator. 3-14oz single and double coated paper cups can be customized according to customer requirements. It is a fully automatic paper cup forming equipment, through multi-row automatic paper feeding, paper anti-return device (to ensure accurate positioning), ultrasonic or copper strip welding, mechanical hand paper tube transfer, oil injection, bottom punching, bottom folding, preheating, and rolling Continuous processes such as flower and cup unloading can stably produce paper cups of various specifications. It is a paper cup equipment independently developed by our company that has undergone comprehensive technical improvements to improve the stability of the whole machine.
